Web Direct UI Issues

I have developed an application and trying to configure for Filemaker pro web direct now what I am facing is that the paddings of the title header's which I have set in my desktop version are not displaying the accurate results in the web direct. secondly, the buttons in the top navigation are set to move on the different layout, in the web direct when I click on these buttons to go to some other layout it first flashes and the move. This behavior of the buttons is totally wearied because it distracts the user.
